I've recently tried getting pretty tables in LaTeX export using Eric
Schulte's function from Worg:

   http://orgmode.org/worg/org-contrib/babel/languages/ob-doc-LaTeX.html#sec-5_2

The problem is that passing the table to the function produces an
error, specifically "wrong type of argument: listp".

Any ideas about what to do differently? Here's a quick example:

* Test Table
Have a look at Table \ref{tab:example}.
#+srcname: es-booktabs
#+begin_src emacs-lisp :var table='((:head) hline (:body)) :exports none
(flet ((to-tab (tab)
              (orgtbl-to-generic
               (mapcar (lambda (lis)
                         (if (listp lis)
                             (mapcar (lambda (el)
                                       (if (stringp el)
                                           el
                                         (format "%S" el))) lis)
                           lis)) tab)
               (list :lend " \\\\" :sep " & " :hline "\\hline"))))
 (org-fill-template
  "
\\toprule
%table
\\bottomrule\n"
  (list
   (cons "table"
         ;; only use \midrule if it looks like there are column headers
         (if (equal 'hline (second table))
             (concat (to-tab (list (first table)))
                     "\n\\midrule\n"
                     (to-tab (cddr table)))
           (to-tab table))))))
#+end_src
#+srcname: tab-example
#+begin_src org :results replace :exports none
      ,|            |   | Column Player |     |
      ,|------------+---+---------------+-----|
      ,| /          | < |               | >   |
      ,|            |   | A             | B   |
      ,| Row Player | A | 1,2           | 3,4 |
      ,|            | B | 5,6           | 7,8 |
#+end_src
#+begin_src latex :noweb yes
\begin{table}[htb!]
  \centering
  \caption{A test table}
  \label{tab:example}
  \begin{tabular}{rl}
    <<es-booktabs(table=tab-example)>>
  \end{tabular}
\end{table}
#+end_src
